There is a 20 - 30% drop in performance for me since yesterday

is this due to increasing difficulty? or do I have issues with my cards?

yes thats the diff

I'm saying this because I tried with my friend who has 7970s too. He gets 19-20 hpm. He restarted his miner instances now, and he also get low hpm s like me. He said its now 14-16 Is that coincidence ?

[reorder]

Yes, I am doing like that. I am running with 4 different miner instances like 0-1-2-3 with different .bat's. But still no change :/

Regarding activity, the algorithm prevents full utilization of cores: they have to spend significant time loading/storing values to VRAM which is terribly slow comparing to just calculations. Besides, load distribution is uneven over time, this is why you observe the sawtoothed load chart. Still, the hpm seems too low for 7970, any chance you could try Linux?

Is there any relation with increased difficulty and hpm ? Now difficulty is 0.00006042 is there any chance low hpm because of rising diff ?

No, pool's share difficulty has not changed. Besides, hpm/wpm does not depend on it.

I had been getting the solid 19ish hpm on my 7970 that i posted before, but i noticed that my hpm dropped closer to 14 over the last few hours on my local client.   rebooted and saw no change. I fired up CGminer to test scrypt and my card hashes away normally at that.  Any thoughts? 

I was wondering too if the difficulty affects HPM with mmc

@reorder,
trying to get the miner working on a fresh ubuntu 12.04 install.

Do you have any clue why it's states "out of ressources" ?

VLIW architectures (5xxx and 6xxx) seem to not work with the miner, I am still figuring this out.

I also have some problems with my 7970s. I can only get 55% activity with my 4 GPUs. I get 14 hpm and 13 wpm with each card. I should get 19-20 with these cards. Is there any way to run this program with full activity ? How can I fix this problem ? If I use CGMiner, I can get maximum performance but with this program I only get half of my performance. What should I do ? (I already tried registery fix)

Please try running 4 miner instances, one for each card.

Hi I have two Gigabyte AMD 7970 GPU and the issue I am having is that it will mine for a few hours and then activity for the GPU's on the AMD VISION Engine Control Center goes down to 0%. When it is mining activity is 99%. Then I look over at the command prompt to see if it shows any sort of error and it doesn't show any sort of error

It just shows what the last share was like the hpm and at what time.

Is anyone having this issue or have any idea what is going on? Also clock settings for GPUs are 975 and 1255 for memory.

I'd suspect card hanging due to overheat here.

It was off for 7 hours while I slept and the mining program was open it just wasn't mining. Shouldn't it start back up on its own after 7 hours of "cooling?"

I went in and manually closed the mining program and restarted it again. It just gets really annoying because I have to keep doing this every few hours.

Any recommendation as to what can be done to stop this? Thanks for your response!!

Have you tried registry fix? My 7970s and 7850s were behaving same.

When (if) the card hangs, it does not tell miner something went wrong, so the miner can only sit there and wait for response. Perhaps you have to force your fans to always run at 90-100% speed.
